These relations are examined in this chapter. In the first part, culture and standard of life are described. Then, the main energy forms and sources are discussed, including fossil fuels, non-fossil resources, renewable energy and electricity. Energy use is described, and its relation to population and urbanization for different countries is examined. The environmental impact of energy use is described, and such environmental concerns as global climate change, stratospheric ozone depletion and acid precipitation are discussed. Then, the impact of energy use on society, culture, standard of life and sustainability is discussed, and the task of achieving sustainable development described. Finally, possible energy-use modifications to improve standard of life and culture are addressed, including increased efficiency, fuel and energy-resource substitution, strategic planning, and the use of exergy analysis and other second-law analysis techniques. The differences between developing and developed countries are addressed throughout the chapter. 1. Introduction In early civilizations, people relied extensively on fire. They burned wood to obtain sufficiently high temperatures for cooking and heating, as well as for melting metals, extracting chemicals and converting heat to work. During combustion, the carbon and hydrogen in wood combine with oxygen (O2) to form carbon dioxide (CO2) and water (H2O), respectively. The CO2 is then absorbed by plants and converted back to carbon, thereby becoming available for use as a fuel again. Since wood proved inadequate to meet all fuel demands and had other limitations, the use of fossil fuels (e.g., oil, coal and gas) began, at the time of the Industrial Revolution. These energy choices have had a strong influence on cultural and economic development and the standard of life achieved (including the state of the environment). For example, using fossil fuels has increased the CO2 concentration in air (see Table 1). Despite past warnings about the risks associated with emissions of greenhouse gases such as CO2, significant actions to ©Encyclopedia of Life Support Systems (EOLSS) THEORY AND PRACTICES FOR ENERGY EDUCATION, TRAINING, REGULATION AND STANDARDS – Energy, Culture and Standered of Life– Marc A. Rosen reduce environmental pollution have not been taken and many researchers now believe that global warming is occurring. This historical discussion demonstrates that energy, culture and standard of life are linked. The relations between these areas are often complex and sometimes difficult to discern, for both developing and developed countries. Historical data on global energyresource use and related environmental emissions and impacts, from 1860 to the present, are given in Table 1. 1860 1880 1900 Year 1920 1940 1960 1980 2000 U SA NE M SC PL O E – C EO H AP LS TE S R S Energy-resource use Global primary energy supply (millions of barrels of 0.3 3 13 18 20 42 110 170 oil equivalent per day) Global fossil fuel use (millions of tons of oil equivalent per day) All fossil fuels 2400 6000 8000 Oil 800 2800 3400 Coal 1500 1800 2500 Energy-related emissions Carbon emissions from burning fossil fuels (million tons) World 2400 5000 6600 Industrial countries 1500 2600 3000 Developing countries 470 1100 2800 Former East Bloc countries 500 1200 700 Energy-related environmental impacts Atmospheric CO2 concentration (parts per million) 283 290 292 298 308 311 330 370 14.5 14.6 14.8 14.7 15.0 15.0 15.1 15.3 Average temperature at earth’s surface (°C) a Data are only available in source for last half century for items missing earlier data.

Selected Data for Energy-Resource Use and Energy-Related Emissions and Impactsa Culture is usually loosely thought of as the form and stage of intellectual development or civilization. Energy choices are sometimes dependent on a society’s culture, while at other times energy-related factors contribute to cultural changes and development. Standard of life is often taken to be the degree of material comfort available to a community. The availability of energy resources (of sufficient quantity, quality and type) and the ability to utilize those resources have a strong influence on a society’s standard of life. Yet the standard of life attained has a feedback effect on energy issues. For example, societies with a high standard of life are likely to have good education ©Encyclopedia of Life Support Systems (EOLSS) THEORY AND PRACTICES FOR ENERGY EDUCATION, TRAINING, REGULATION AND STANDARDS – Energy, Culture and Standered of Life– Marc A. Rosen systems and extensive research and development undertakings that permit the development of energy technologies capable of harnessing energy resources more efficiently and with less environmental impact. Environmental impact is often a significant consequence of energy use and strongly affects culture and standard of life. Environmental issues also affect the sustainability of a country’s development in the longer term and thus are an important consideration. U SA NE M SC PL O E – C EO H AP LS TE S R S In this chapter, the relations between energy, culture and standard of life are examined. First, culture and standard of life are described. Then, energy use, in the world and in countries, is described and its relation to population and urbanization are covered. The main energy forms and sources discussed are fossil fuels, non-fossil resources, renewable energy and electricity. Environmental concerns are discussed and the environmental impact of energy use is described. Then, the impact of energy use on society, culture, standard of life and sustainability is discussed, and needs for achieving sustainable development in countries are described. Finally, possible energy-use modifications to improve standard of life and culture are covered. The differences between developing and developed countries are addressed throughout the chapter. This is the lead chapter for a series of chapters on energy, culture and standard of life (see Natural and Additional Energy). The chapter is intended to present a broad summary and evaluation of each of these areas and the interactions between them. For context, it is noted that this series of chapters on energy, culture and standard of life fall within the general theme of “basics of energy and energy-related education and training, organizations and standards.” Topics in this theme include fundamentals such as thermodynamics, electromagnetism and nuclear physics, as well as more general subjects such as energy-related education and training, international information systems and codes and standards. 2. Culture and Standard of Life An understanding of culture and standard of life is crucial to this chapter. However, these concepts often have different meanings to different people, and are imprecisely understood. Thus, for clarity, some definitions of these concepts are presented and discussed here. Culture is a concept not easy to explain. Culture is defined in a general sense by the Oxford dictionary as the “particular form, stage, or type of intellectual development or civilization.” The Webster’s dictionary defines culture more specifically as “the concepts, habits, skills, art, instruments, institutions, etc. of a given people in a given period” or, more simply, “civilization.” Some of the many factors that contribute to a culture include its standards for greetings and dress, social taboos, customs and traditions, crafts, local foods and dishes, and architecture. Standard of life (or living) is a relative measure and not easily quantified. Standard of living is defined as the “degree of material comfort available to person or class or community” (Oxford dictionary), and as “a level of subsistence, as of a nation, social class, or person, with reference to the adequacy of necessities and comforts in daily life” ©Encyclopedia of Life Support Systems (EOLSS) THEORY AND PRACTICES FOR ENERGY EDUCATION, TRAINING, REGULATION AND STANDARDS – Energy, Culture and Standered of Life– Marc A. Rosen (Webster’s dictionary). Some of the many factors that contribute to standard of life are listed in Table 2. In that table, some key social and economic indicators for selected countries are given.

Key Socio-Economic Indicators for Selected Latin and Caribbean Countries (1998) Culture and standard of life are not independent. They are related and details of either can affect the other. For example, a society with a high standard of life may have ample free time to devote to cultural development and consequently may develop a wide range of arts and skills, while a society with a lower standard of life may focus on the development of practical skills associated with basic necessities. Also, the cultural choices made by a society (e.g., placing a high value on economic wealth) can affect the standard of life achieved. Energy issues clearly have an impact on culture and standard of life, while these topics in turn often affect energy choices. An abundance of energy resources can help a society achieve a high standard of living in terms of wealth, simply through harvesting the resources, although problems such as energy-related environmental degradation can also result in such situations. By extension, cultural choices, directions and ©Encyclopedia of Life Support Systems (EOLSS) THEORY AND PRACTICES FOR ENERGY EDUCATION, TRAINING, REGULATION AND STANDARDS – Energy, Culture and Standered of Life– Marc A. Rosen development each can be affected by availability of energy resources. Yet the possession of abundant energy resources does not always lead to high living standards, and countries that have little or no domestic energy resources can often achieve high standards of life, often through developing a culture that highly values learning, knowledge and innovation. We further examine the impact of energy use on culture and standard of life in Section 5. First, however, energy use and its impact on the environment are discussed in detail in the next two sections. 3. Energy Use 3.1. Population and Energy Use U SA NE M SC PL O E – C EO H AP LS TE S R S 3.1.1. The World The world population is expected to increase, even if the birth rates decline so that the world population becomes stable, from 5.3 billion in 1990 and 6.0 billion in 2000, to about 10.5 billion in 2050. Thus, compared to 1990, world population is expected to double by the middle of the 21st century. Economic development will almost certainly continue to grow in the future. Global demand for energy services is expected to increase from 1990 levels by as much as an order of magnitude by 2050, while primary-energy demands are expected to increase by 1.5 to 3 times. In addition to increasing energy requirements, this anticipated population growth is likely to lead to increasing energy-related environmental problems such as acid precipitation, stratospheric ozone depletion and global climate change (the greenhouse effect). Simultaneously, concern regarding these energy-related environmental impacts is likely to increase. These discussions demonstrate that energy is one of the main factors that must be considered in discussions of sustainable development, along with population and environmental degradation. 3.1.2. Developing Countries The world population share of developing countries, which was less than 70% in 1960, is about 77% today, and is expected to reach about 85% by 2050. Although developing countries, with their present population of over four billion, represent about over threequarters of the world’s population, they are responsible for only a quarter of global energy use. Demographers predict that the total world population will top eight billion by 2005, and that roughly three-quarters of these people will continue to live in developing countries. The ability to provide energy services for the developing world must grow considerably to meet the extra demands expected in these countries and to ensure that their economic development is not constrained. ©Encyclopedia of Life Support Systems (EOLSS) THEORY AND PRACTICES FOR ENERGY EDUCATION, TRAINING, REGULATION AND STANDARDS – Energy, Culture and Standered of Life– Marc A. Rosen The population growth in developing countries is likely to lead not only to increasing energy requirements, but also to increasing energy-related environmental impact. Much of the population growth for developing countries will occur in metropolitan areas where there is a concentration of vehicles, industries and other emission sources, as well as significant deforestation. 3.2. Effect of Urbanization on Energy Use In order to develop an understanding of the issues associated with global CO2 emissions and other environmental impacts, the relationship between urban growth and energy use must be appreciated. The energy needs of cities are large and increase with both urban growth and industrial development. U SA NE M SC PL O E – C EO H AP LS TE S R S Energy needs, however, are not the same everywhere. Energy policies and programs should account for this spatial differentiation. In some locations where wood is used as a fuel, increased efficiencies of wood stoves and charcoal kilns are required to make wood supplies sustainable. Such innovations may require greater education and information-dissemination efforts in many smaller cities, which appear to face greater wood fuel shortages. In general, urbanization entails not only major changes in land-use patterns, but also shifts in the ways societies use energy. The transition away from “traditional fuels” (e.g., firewood, charcoal, crop residues) to such modern fuels and energy forms as petroleum, coal, natural gas and electricity is accelerated with urbanization. Urbanization is a growing trend in many developing countries, along with increased urban energy demand. 3.3. Energy-Use Growth Patterns 3.3.1. Worldwide Trends Energy demand has grown rapidly since the sudden decrease in oil prices in the mid1980s, e.g., world energy demand grew by 17% between 1986 and 1992. Even allowing for potential new energy resources, many feel that present growth in energy demand may not be sustainable. Many methods are used to predict future energy use patterns. One widely recognized method is that of the International Energy Agency (IEA). The IEA uses two cases to project future energy use: - the capacity constraints case, in which trends in past behavior are assumed to continue to dominate future energy-consumption patterns, and - the energy savings case, in which greater energy-efficiency improvements are assumed to occur than suggested by past behavior. World energy use projected using the IEA’s capacity constraints case is shown in Table 3. In this case, world demand for primary energy increases by more than 44% between 1992 ©Encyclopedia of Life Support Systems (EOLSS) THEORY AND PRACTICES FOR ENERGY EDUCATION, TRAINING, REGULATION AND STANDARDS – Energy, Culture and Standered of Life– Marc A. Rosen and 2010, corresponding to an average annual rate of about 2.1%, to 11,489 million tonnes of oil equivalent (Mtoe). The average annual growth rate through this period for natural gas is 2.5%, the fastest among all fossil fuels.
